The "calorific value" (assuming you mean heat of combustion) of sawdust varies somewhat depending on the kind of wood the sawdust came from. It is also influenced by the amount of moisture in the sawdust - if the sawdust is not dry, some of the heat is absorbed to heat up the water and evaporate it instead of being given off as heat. The heating value of sawdust from softwoods (like pine) is typically about 20-22 MJ kg-1 and of hardwoods (like oak and maple) about 19-21 MJ kg-1. Note that despite the similarities of these ranges, there are plenty of woods that will yield higher and lower values; for example tests on poplar trees have a range of values of 19·49 MJ kg-1.

Calorific value is the percentage of heat generated by a unit of substance. Some substances have high calorific value , while others have low calorific value.
You can convert gross calorific value (GCV) to net calorific value (NCV) by subtracting the latent heat of vaporization of water formed during combustion from GCV. The equation for this is NCV = GCV - 2.5 x (9 x % H2 - % O2), where % H2 is the percentage of hydrogen in the fuel and % O2 is the percentage of oxygen in the fuel.
GVC stands for gross caloric value. Gross calorific value may be converted to net calorific value by using the following equation, Net calorific value = Gross calorific value - (10.02 x Percent Moisture)
The calorific value of fuel is the quantity of heat produced by its combustion at a constant pressure and under normal conditions. For diesel, the calorific value is 44,800.
The calorific value for petrol is 47 300 kJ/kg.
